Christine Keeler, who died on Monday, was at the centre of the 1960s Profumo Affair.

She had a relationship with British Minister for War John Profumo.

At the same time, she was seeing a Soviet diplomat, sparking security concerns.

Profumo lied about the affair in Parliament and later had to resign.

The scandal damaged the government and led to its downfall.

Publicity around the events is seen as a watershed moment in British culture.

The model at the centre of a scandal, which rocked the British political and social establishment, and ended an age of deference in British culture, has died.

Christine Keeler, a young woman catapulted into British history through a scandal involving UK cabinet minister John Profumo in the 1960s, was confirmed dead yesterday by her family. She was 75.

Keeler was a model and showgirl who spent time in London dance clubs, where she came into the orbit of British high society along with other young women in her position. She was 19 at the time.

Her life became the object of a Cold War political scandal when it became public knowledge that she had been sexually involved with Profumo — then Britain's minister for war — while doing the same with a Soviet diplomat based in London.

Opposition MPs alleged that having such a close link between a senior government minister and a rival power presented a security risk, predicated on the idea that Keeler could be a conduit to leak secrets to the Russians.

Profumo's resignation was a major blow to Macmillan's government, and was one of several factors which led to his resignation later that year, and a loss for the Conservative Party in 1964 to Harold Wilson.

Keeler went on as a minor celebrity in the UK, appearing in interviews and in newspapers based on the scandal, which produced books, the 1989 film "Scandal," and the West End musical "Stephen Ward."

Some official papers relating to the case are due to remain classified until 2046, 100 years after the birth of Mandy Rice-Davies, Keeler's roommate and the youngest figure in the scandal.
